Here is a useful and enjoyable gift for the whole family: a friendly and wise conversation between a great astrophysicist and his granddaughter.

One summer, when the nights are clear, the famous astrophysicist grandfather explains to his fourteen-year-old granddaughter the mysteries of the sky. With simple language, he describes what we know and what we still have to learn about the Sun, the Moon, the Earth, the stars, the infinite universe... Besides the specialized knowledge and answers one can get from this booklet, it takes us on a journey through space, where romance and poetry are not absent.
